Procedural Mouth Animator for VRM4U

voice.tech.demo.mp4

This fork adds a procedural mouth animation utility for morph targets on VRM skeletal meshes. It makes use of various submix analysis functions included in Unreal Engine. Because it analyzes the formants that are most present in speech, this solution is language agnostic, creates convincing mouth shapes for vowel sounds, and correctly closes the mouth at each syllable.
